S02E62: Tactics

Dino's unsuspected guest is revealed to be Squalo, who Dino saved instead of Yamamoto and brings to see the sky match. Yamamoto along with Gokudera propose a trade between Mammon and Bel, which turns out to be a well played trick but is countered by Mammon's illusions which binds both Yamamoto and Gokudera, Gokudera of which drops the remaining rings. Tsuna and Xanxus have a struggle where Xanxus powers up, which seems to turn the tide of the battle. Tsuna and Xanxus then charge at each other which results in a huge explosion. After the smoke clears, Tsuna's Zero Point Breakthrough froze Xanxus's hand; revealing he has mastered the First's technique.
